While going through another members steps for resolving misfires and I realized something pretty interesting. The M56 engines do not seem to have a CCV. Please correct me if i am wrong. As you can see in the real OEM diagram, the dipstick tube goes straight into the oil pan.

I guess thats one less thing for me to check while trying to find the reason for my misfires

Also the air intake boots seem to have a much better design which would limit the usual cracks at the bottom. These have more meat on them and less of the folds where the cracks usually occur (I think).
